Wireless communication network authentication
19 Dec 23
A method of authenticating a device subscribed to a first wireless communication network on a second wireless communication network, the method including: deriving at a node within the first wireless communication network a set of one or more network keys for the second wireless communication network from one or more network keys of the first wireless communication network that uniquely identify the device within the first wireless communication network; communicating the derived set of one or more network keys to the device; storing a first copy of the derived set of one or more network keys within an identification module at the device and a second copy of the derived set of one or more network keys within a secure area of the device; and authenticating the device on the second wireless communication network using the second copy of the derived set of one or more network keys stored in the secure area of the device.

Utility
Task dispatching system
23 Nov 20
An assignment system for allocating service providers to required services, comprising: a data processing unit; a data store storing a plurality of allocation processing routines each defining a respective algorithm for determining in respect of a service which of a series of potential providers of that service is/are preferred to provide the service; and an allocation mode selector configured to access a data store storing a list of required services and attributes of each required service, to select in dependence on the attributes of one of those services one of the allocation processing routines and to cause that allocation processing routine to be executed in respect of that one of the services by means of the data processing unit so determine which of a series of potential providers of the service is/are preferred to provide that service.

Utility
Pattern matching machine with mapping table
27 Apr 20
A computer implemented method for generating a pattern matching machine for identifying matches of a plurality of symbol patterns in a sequence of input symbols, the method comprising: providing a state machine of states and directed transitions between states corresponding to the plurality of patterns; applying an Aho-Corasick approach to identify one or more mappings between states in the event of a failure, of the state machine in a state and for an input symbol, to transition to a subsequent state based on the directed transitions of the state machine, characterised in that one of the symbol patterns includes a wildcard symbol, and a mapping for a state representing pattern symbols including the wildcard symbol is provided in a hash table referenced based on a key, the key being based on a unique identifier of the state and the input symbol to be received, by the pattern matching machine in use, to constitute the wildcard symbol.

Utility
Content designation for a content delivery network
16 Mar 20
A method for designating a class of data content for determining how the content will be handled by a content delivery network (CDN) into one of: a transport designation by which content is transported from an entrance node to one or more edge nodes; a caching designation by which the content is stored at one or more edge nodes; and a hybrid designation by which content is stored at a node in the CDN for subsequent transport to one or more edge nodes in the CDN, the method comprising: determining a set of one or more transport designation options; determining a set of one or more caching designation options; determining a set of one or more hybrid designation options; determining a normalised measure resource requirement for each of the transport, caching and hybrid designation options; and selecting one designation option for the class of content from all of the transport, caching and hybrid designation options by an optimisation function for selecting the designation option based on the determined normalised resource requirement for each option.

Utility
Pattern matching machine for repeating symbols
13 Jan 20
A method for generating a pattern matching machine for identifying matches of a symbol pattern in a sequence of in put symbols, the received symbol pattern including an indicator that one or more symbols in the symbol pattern repeat as repeated symbols, the method comprising: generating a plurality of symbol patterns for the received symbol pattern, each generated symbol pattern being equivalent to the symbol pattern for a different number of repetitions of the repeated symbols, wherein the plurality of generated symbol patterns comprise all possible symbol patterns equivalent to the received symbol pattern up to a predetermined maximum length of a generated symbol pattern.
